Answer:its 12

Step-by-step explanation:

The number can each term of the equation be multiplied by to eliminate the fractions before solving is 12, the correct option is D.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

Equation 6 – x + = x + 5

Now,

the least common multiple of 2 and 3, which are the denominators of the fractions in the equation. Multiplying each term by 12 will clear the fractions and result in an equivalent equation without fractions. For example: 12(6 - x + ) = 12(x + 5) 2 3 Simplifying, we get: 72 - 12x + 4 = 12x + 60. This is an equation without fractions that can be solved for x.

Therefore, by the given equation the answer will be 12.

Answer:

50%

Step-by-step explanation:

The total number of marbles is 7 + 3 + 2 + 8 = 20

Blue or red means that the total on any one draw is 7 + 3 = 10

You would expect to draw blue or red 1/2 the time.

Out of 150 throws, you would get 1/2 * 150 which is 75 but that is not what you are asked.

% = (1/2 ) * 100  = 50% of the time

Answer:

AC ≈ 10.5 cm (1 dec. place )

Step-by-step explanation:

Given

tan55° = [tex]\frac{15}{b}[/tex]

Multiply both sides by b

b × tan55° = 15 ( divide both sides by tan55° )

AC = b = [tex]\frac{15}{tan55}[/tex] ≈ 10.5 cm

Answer:

54 is x

Step-by-step explanation:

Sounds like you describing vertical angles. Vertical angles are congruent so that means 2x+2=3x-52

2=1x-52. Subtracted 2x on both sides

54=1x. Added 52 on both sides

54=x. Since 1 times x is x

Answer:

A. 22.5° AND D. 22°30’

Step-by-step explanation:

First of all, it's the correct answer on ap*x

To convert π/8 to degrees, replace π with 180°.

π/8 = 180°/8 = 22.5° (A)

Convert 22.5° to degrees minutes seconds

22.5° = 22°30’ (D)

To convert an angle from radians to degrees, multiply by 180/π. The angle measuring π/8 radians is equal to 22.5°.

To convert an angle from radians to degrees, we use the conversion factor 180/π. So, an angle of π/8 radians is equal to:

Therefore, the angle measuring π/8 radians is equal to 22.5°.

Step-by-step explanation:

The ordered sequence from greatest to least for the numbers 5.505, 5.55, 0.555, 5.005 is: 5.55, 5.505, 5.005, 0.555. This is done by comparing the values by comparing the digits at each decimal place, from left to right.

To order the numbers 5.505, 5.55, 0.555, 5.005 from greatest to least, we would look at the digits in their decimal places from left to right. Starting from the first place, 5.55 is the largest as it is the only number with a '5' in the hundredth place. Next, both 5.505 and 5.005 have '5' in the units place. However, 5.505 has a '5' in the thousandth place, while 5.005 has '0'. Therefore, 5.505 is larger. Finally, 0.555 is the smallest as it is less than 1. So, the numbers, ordered from greatest to least are: 5.55, 5.505, 5.005, 0.555.

Step-by-step explanation:

Answer:

The actual distance between the two cities is 28 kilometers

Step-by-step explanation:

A map has a scale of 3.5 inches = 20 kilometers

Distance between two cities on the map = 4.9 inches

We can use the unitary method in this question to get the actual distance between two cities

∵ 3.5 inches on the map = 20 kilometers

∴ 1 inch distance on the map = [tex]\frac{20}{3.5}[/tex] kilometers

∴ 4.9 inches on the map = [tex]\frac{20}{3.5}\times 4.9[/tex]

                                         = 28 kilometers

Therefore, the actual distance between the two cities is 28 kilometers.

Answer:

B. [tex]8,000-24x[/tex].

Step-by-step explanation:

We have been given that Desmond wants to sell his car that he paid $8,000 for 2 years ago. The car depreciated, or decreased in value, at a constant rate each month over a 2-year period.

Since the value of car depreciates at a constant rate each month, so the value of car depreciated in 2 years would be [tex]2\times 12=24[/tex].

There are 24 months in two years, so value of car depreciated in 2 years would be 24x.

The initial value of car is $8,000, so value of car after 2 years would be [tex]8,000-24x[/tex].

Therefore, option B is the correct choice.

Answer:

B. Domain: -5/2

Range: 1/2

Step-by-step explanation:

If you plug -5/2 for x, it becomes no solution due to the zero in the denominator.

If you plug 1/2 for y and let your calculator do its thing, it becomes no solution.

Because these values cannot be solved for in the equation, they are excluded from the domain and range.

Edit: I got it correct on the Unit Review on edge.

The domain and range values that are excluded from the function given as  f ( x ) = ( x + 3 ) / ( 2x + 5 ) are x = -5/2 and y = 0

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

The range is the set of outputs of a relation or function. In other words, it's the set of possible y values. Recall that ordered pairs are of the form (x,y) so the y coordinate is listed after the x. The output is listed after the input.

Given data ,

The function f(x) = (x + 3)/(2x + 5) has certain values that are excluded from its domain and range.

The function f(x) is defined for all real numbers except for the values of x that make the denominator (2x + 5) equal to zero.

Therefore, the values of x that are excluded from the domain of f(x) are those that satisfy the equation 2x + 5 = 0.

2x + 5 = 0

2x = -5

x = -5/2

The range of f(x) is all real numbers except for zero (0), because it is never equal to zero.

Hence , the values excluded from the domain of f(x) are x = -5/2 and the values excluded from the range of f(x) are y = 0

The expression √-15√-4 is simplified to -2√15 using the imaginary unit i, where i represents the square root of -1. We do this by simplifying each square root with i and then multiplying the results together, remembering that i^2 equals -1.

To simplify the expression using i, where i is the imaginary unit we define as the square root of -1, we have √-15√-4. We can start by simplifying each square root separately using i:

√-15 = √(15 × -1) = √15 × √i = √15i

√-4 = √(4 × -1) = √4 × √i = 2i

Now, you simply multiply the two results together:

√15i × 2i = (√15 × 2) × (i × i) = 2√15 × i²

Since i² equals -1, our expression simplifies to:

2√15 × -1 = -2√15

Therefore, the simplified form of the expression √-15√-4 using i is -2√15.

So I simplify the expression and it is..
